一、初一英語(yǔ)語(yǔ)法——詞法
1、名詞
A)、名詞的數(shù)
我們知道名詞可以分為可數(shù)名詞和不可數(shù)名詞,而不可數(shù)名詞它沒有復(fù)數(shù)形式,但可數(shù)名詞卻有單數(shù)和復(fù)數(shù)之分,復(fù)數(shù)的構(gòu)成如下:
一)在后面加s。如:fathers, books, Americans, Germans, apples, bananas
二)x, sh, ch, s, tch后加es。如:boxes, glasses, dresses, watches, wishes, faxes
三)以輔音字母加y結(jié)尾的變y為i再加es 如:baby-babies, family-families, duty-duties, comedy-comedies,documentary-documentaries, story-stories;
以元音字母加y結(jié)尾的直接加s。如:day-days, boy-boys, toy-toys, key-keys, ways
四)以o結(jié)尾加s(外來詞)。如:radios, photos, 但如是輔音加o的加es:如: tomatoes西紅柿, potatoes馬鈴薯

九)合成的復(fù)數(shù)一般只加主要名詞,多數(shù)為后一個(gè)單詞。如:action movie-action movies, pen pal-pen pals; 但如果是由man或woman所組成的合成詞的復(fù)數(shù)則同時(shí)為復(fù)數(shù)。如:man doctor-men doctors, woman teacher-women teachers
十)有的單復(fù)數(shù)意思不同。如:fish魚 fishes魚的種類, paper紙 papers報(bào)紙,卷子,論文, work工作 works作品,工廠, glass玻璃 glasses玻璃杯,眼鏡, orange桔子水 oranges橙子, light光線 lights燈, people人 peoples民族, time時(shí)間 times時(shí)代, 次數(shù), chicken 雞肉 chickens 小雞

三)由and并列的名詞所有時(shí),如果是共同所有同一人或物時(shí),只加最后一個(gè)’s,但分別擁有時(shí)卻分別按單數(shù)形式處理。如:Mike and Ben’s room邁克和本的房間(共住一間),Mike’s and Ben’s rooms邁克和本的房間(各自的房間)

3. 形容詞的用法:
形容詞用以修飾名詞,表示人或事物的特征。在句中可以作定語(yǔ)、表語(yǔ),用于限定被修飾語(yǔ)的特征,如長(zhǎng)短、大小、重量、顏色、高矮、胖瘦、新舊等。
The little girl is very pretty. 這個(gè)小女孩很好看。

4、人稱代詞:
是用來表示人的代詞,有單數(shù)和負(fù)數(shù)之分,有主格和賓格之分。人稱代詞的主格在句中作主語(yǔ);人稱代詞的賓格在句中作賓語(yǔ),是作動(dòng)詞或介詞的賓語(yǔ)。
主格:I, we, you, he, she, it, they在句子中作主語(yǔ)
賓格:me, us, you, him, her, it, them在句子中作
賓語(yǔ)
He and I are in the same class. 我和他在同一個(gè)班級(jí)。
Can you see them in the street? 你能看見他們?cè)诮稚蠁?
5、可數(shù)名詞和不可數(shù)名詞
英語(yǔ)中名詞分為可數(shù)名詞和不可數(shù)名詞。凡是可數(shù)計(jì)數(shù)的名詞叫做可數(shù)名詞;凡是不可以計(jì)數(shù)的名詞叫做不可數(shù)名詞。
(1)可數(shù)名詞分為單數(shù)和復(fù)數(shù)兩種形式?蓴(shù)名詞前可以用不定冠詞、數(shù)詞或some many等修飾。如:a man a desk an apple an orange some books some children tow pens
(2)不可數(shù)名詞沒有復(fù)數(shù)形式,前面不能用不定冠詞、數(shù)詞或many等詞語(yǔ)修飾,但可以用some a little much等詞語(yǔ)來修飾。有時(shí)可以與一些量詞短語(yǔ)搭配,這些量詞短語(yǔ)中的名詞一般是可數(shù)的,有單數(shù)形式,也可以有復(fù)數(shù)形式。如:some water a little milk much food a piece of bread tow bottles of ink some glasses of water
6、祈使句
祈使句用來表示請(qǐng)求、命令等,句中沒有主語(yǔ),肯定形式由謂語(yǔ)或者謂語(yǔ)+賓語(yǔ)(+賓語(yǔ)補(bǔ)足語(yǔ))構(gòu)成,否定形式則在句前加Don’t.
Stand up, please. 請(qǐng)起立。

can的用法:
can是情態(tài)動(dòng)詞,表示“能,會(huì),可以,被允許等”,其后接動(dòng)詞原形,否定形式為cannot,可縮寫為can’t.
She can speak Japanese. 她會(huì)講日語(yǔ)。

Can you spell your name? 你會(huì)拼寫你的名字嗎?
7、現(xiàn)在進(jìn)行時(shí)態(tài):
概念:表示現(xiàn)在(說話瞬間)正在進(jìn)行或發(fā)生的動(dòng)作,也可以表示目前一段時(shí)間內(nèi)或現(xiàn)階段正在進(jìn)行的活動(dòng)。
結(jié)構(gòu):由be動(dòng)詞(am, is, are) + 動(dòng)詞ing構(gòu)成,其中be動(dòng)詞要與主語(yǔ)保持性數(shù)一致。
Mary is flying a kite in the park. 瑪麗正在公園里放風(fēng)箏。
--What are you doing now? 你現(xiàn)在在干什么?
--I’m reading English. 我正在讀英語(yǔ)。
Are they drawing the pictures now? 他們正在畫畫嗎?
動(dòng)詞現(xiàn)在分詞是動(dòng)詞原形變化而來的,規(guī)則變化如下:
動(dòng)詞ing形式叫動(dòng)詞現(xiàn)在分詞,其構(gòu)成如下:
1)直接在動(dòng)詞后加ing
play—playing, do—doing, talk—talking, sing--singing
2)以不發(fā)音的字母e結(jié)尾的動(dòng)詞,先去e,再加ing
make—making, write—writing, have—having, take—taking
3)以重讀閉音節(jié)結(jié)尾的動(dòng)詞且詞尾只有一個(gè)輔音字母,應(yīng)雙寫這個(gè)輔音字母,再加ing
run—running, stop—stopping, put—putting, swim—swimming
注意對(duì)現(xiàn)在進(jìn)行時(shí)態(tài)的判斷。判斷一個(gè)英語(yǔ)句子用什么時(shí)態(tài),主要看句子的時(shí)間狀語(yǔ),一般說來,每種時(shí)態(tài)都有與之相對(duì)應(yīng)的時(shí)間狀語(yǔ)。現(xiàn)在進(jìn)行時(shí)表示現(xiàn)在(說話瞬間)正在進(jìn)行或發(fā)生的動(dòng)作。因此,這個(gè)時(shí)態(tài)最常用的時(shí)間狀語(yǔ)是now;但有不少句子并沒有now,只能通過提示語(yǔ)如look、listen等或者通過上下文來確定用現(xiàn)在進(jìn)行時(shí)。
She is cleaning her room now. 她正在打掃房間。
Look! The girl is dancing over there. 看!那個(gè)女孩在那里跳舞。
Can you go and play games with me? 你能和我們一起做游戲嗎?

You have a new English teacher. 你們有了一個(gè)新的英語(yǔ)老師。
It has two big eyes. 它有一雙大眼睛。
Julie and Jack have a nice car. 朱莉和杰克有一輛好看的車。
2)have/has句型與there be句型的比較:兩者都表示“有”,但用法不同。前者表示所屬關(guān)系,即表示“某人或某物有什么”,而后者表示存在,表示“某地有什么”。
They have some new books. 他們有一些新書。
There are some new books on their desks. 他們桌子上有一些新書。

There are a lot of pretty skirts in the shop. 商店里有很多漂亮的裙子。
